Why Coffee Cups Matter: Rethinking Large vs Small in Specialty Cafés

 When we order coffee in cafés, it’s common to see certain drinks on the menu offered in “large” and “small” sizes (and let’s not bring up that brand that contradicts itself). But in reality, most espresso-based drinks already come with a naturally fixed serving size by design. Those so-called size options are often nothing more than a blunt, convenience-driven modification for consumption scenarios. I’ve long felt that cafés perhaps shouldn’t think in terms of “large” or “small” at all, but rather in terms of purpose-specific coffee cups. Today, I want to talk about where this idea comes from.

This isn’t the first time I’ve thought seriously about this topic. Early last year, when a certain brand launched an 8-ounce cortado, it sparked plenty of discussion within the industry. In the world of specialty coffee, the idea of using a purpose-designed cup for each drink reflects a deep respect for coffee culture and the consumer experience. It shifts thinking away from the purely practical logic of “big vs. small” and toward a coordinated design that balances ritual, function, and flavor. That alone makes it something worth serious consideration—and practice—within the industry.

We all know that every classic coffee drink carries an implicit functional logic in its cup design. As the specialty coffee world becomes more refined, we’re seeing more niche, highly specific products emerge to meet the needs of segmented markets. Take the cortado as a simple example. Traditionally, a cortado is served in a cup of around 130 milliliters. This volume precisely matches an espresso-to-milk ratio of roughly 1:1 to 1:2, ensuring that each sip delivers both the richness of espresso and the smoothness of milk. The drink isn’t diluted by excess volume, nor does it lose heat too quickly due to overly thick cup walls. To achieve this balance, a dedicated cortado cup is essential—it best represents the drink as intended. After all, the cup itself is one of the factors that influences flavor and presentation.

If you serve a cortado in a large cup, the extra milk or water disrupts that precise ratio. What you end up with—like an 8-ounce “cortado”—is essentially a latte, and the original design intent of the drink becomes completely blurred. A purpose-specific cup also acts as a kind of “silent language.” When I order a cortado in cafés abroad, one of my main reasons is to evaluate the shop’s level of professionalism through how the drink is presented: the cup, the integration of espresso and milk, and the resulting flavor. When the right cup is used, it often signals to me that the café truly knows what it’s doing—grounded in coffee tradition and attentive to the overall quality of the experience.

At the same time, serving coffee in dedicated cup designs guides customers toward the most appropriate way to enjoy each drink. Coffee is a multisensory experience, engaging sight (presentation), touch (how the cup feels in the hand and its temperature), smell (how aromas are concentrated), and taste (how temperature and texture evolve). The thickness of the rim affects how the liquid meets the lips; the shape of the cup influences aroma release and the stability of milk foam. Material matters too—ceramic retains heat better, while glass highlights visual layers. That’s why many cafés choose glass cups for cortados: to let customers see the beautiful interaction between milk and coffee. In fact, cortado in Spanish literally means “cut,” referring to this very interplay.

Some might argue that using purpose-specific cups for every drink would require owning an overwhelming number of different cups. For small cafés, storing and managing a dozen or more specialized cups can indeed be a significant cost and logistical burden. But this can be approached selectively or in stages. Start with the core classics—espresso, cappuccino, cortado—drinks where cup volume truly matters. Many independent cafés already think deeply about this. You can feel the care they put into matching drink volumes with the right cups. These choices go far beyond whether a cup simply looks good; they reflect careful consideration. This is a sign of specialty coffee culture maturing and becoming more refined.

One drink, one cup—much like using the proper glass for a specific wine. It’s an extension of flavor and a vessel of culture. It represents not just serving a coffee beverage, but presenting a complete coffee work. When I drink a cortado, what I taste isn’t only the precise balance of espresso and milk, but also the sense of ritual and intention behind it. And isn’t that exactly where the true appeal of professional coffee lies?
